That's a multiple / random misfire. Lot's of ways to go on this.. bad plug, wire, coil pack, etc. Then there's this one:
fixed my PO300 code MY350Z COM Forums

code P0303 is a misfire code for cylinder # 3, Possible spark plug, wire/coil or injector problem. P0141, bank1 sensor2, is the upstream oxygen sensor, this code may have been set by the misfire of Cyl #3, the lean condition is being cause by the misfire. Fix the misfire and clear the codes and P0141 should not return. If the vehicle is equipped with Coil over plug system try swapping the coil with any one of the others, test drive and if the misfire code changes to another P0300 code ( P0301, P0302, P0304 etc...) the coil has failed and will need to be replaced.

faulty temperature sensor causing the misfire problem, replace the coolant sensor the misfire problem will be fix.
